It's a long shot and kinda impossible to find, but it will solve your problem.
You'll have to revert to old technology, analogue technology, not digital. this is the problem of modern technology these days. Cohersion, Adaptability and Unified Standards
You'll have to find someone still working on mercury based re-alignment instruments. It's an old analogue system used in the eighties and before. it's 97-98% accurate, but it's 97-98% solution to your problem until the new specs arrive.
Try finding an old-timer in an old shop in some old town. Ask if they still have old school mercury based equipment. they dont need specs, they can do it to any car and and tire combination, takes about an hour longer to do, but they do it.
